Try to map Video BIOS in intel_bios.c
By reading your dmesg, it seems neither the i915 driver nor the Radeon driver
find the Video BIOS. In the i915 case, the card is initialized, but without
output connectors. In the Radeon case, the driver aborts the initialization
process.
Currently, our i915 driver doesn't read the shadow copy of the Video BIOS,
which is available at a fixed location in system memory if the card is the boot
display. I attached patch which tries to map that Video BIOS shadow copy (only
built-tested).
Could you please try it?
